FR5 is one of the official NatHERS Accredited Software packages that can be used by Accredited Assessors to generate official NatHERS Certificates required by Australian planning authorities as part of the Development Application process.
FR5 uses the Commonwealth Scientific and Industrial Research Organisation (CSIRO) Chenath engine to perform the energy calculation engines which is the same engine used by all NatHERS Accredited Software.
